Hi, my name is***** fault can be caused by any one of the modules on the CAN-B network. The most common fault is the rear window modules. You will need to disconnect one module at a time until you locate the module that is bringing the CAN down. Locate the CAN bus connector under the carpet in the area of the right front door sill and do your testing from there. You can unplug one module at a time from the connector to locate the problem.
